CoreWebView2 returned null

Question

I am working on a custom web browser project, but when I try to navigate by using this code, the project generates an error.

    (Controls["webView21"]  as WebView2).CoreWebView2.Navigate("URL goes here");

It said that CoreWebView2 returned null even though I modified the source property without error. What can I do to fix this?

Answer 1

Try to call the EnsureCoreWebView2Async() method before accessing the CoreWebView2 property:

var webViewControl = Controls["webView21"] as WebView2;
await webViewControl.EnsureCoreWebView2Async();
webViewControl.CoreWebView2.Navigate("URL goes here");
